    1. 1. Classifying Matter: Elements, Compounds, and Mixtures
    2. 2. Pure Substances A sample of matter that has definite chemical and physical properties.
    3. 3. Elements Remember: Elements are pure substance that cannot be separated into simpler substance by physical or chemical means. We classify elements into the Periodic table:
    4. 4. Compounds Pure substance composed of two or more different elements joined by chemical bonds. Made of elements in a specific ratio that is always the same Has a chemical formula Can only be separated by chemical means, not physically
    5. 5. Mixtures A combination of two or more pure substances that are not chemically combined. substances held together by physical forces, not chemical No chemical change takes place Each item retains its properties in the mixture They can be separated physically Chem4kids.com
    6. 6. Mixtures vs. Compounds
    7. 7. Can you identify the following? Construct a table in your book with 3 columns, with the headings element, compound, and mixture. You will be shown a series of photos. Can you tell which of the three headings each photo represents? Write the answers into your table. Review: An element contains just one type of atom. A compound contains two or more different atoms joined together. A mixture contains two or more different substances that are only physically joined together, not chemically. A mixture can contain both elements and compounds.
